The best source for GM300s is ebay. They pop up weekly there. Recent auction prices are in the $125 range. Make sure you get the units with the 16 pin connector in the rear. I have over one dozen in service, either as repeater receivers, repeater transmitters, or remote bases. It's a great radio for those purposes; built like a tank.
